About This Book

A practical illustrated field guide that enables identification of North American birds by combining systematic order keys with a color-based key and numerous plates and drawings. It explains how to learn bird names without specimens, describes measurement conventions and abbreviations, offers color illustrations emphasizing field-visible markings, provides systematic tables and bibliographical appendices including nomenclatural changes, and supplies guidance on collecting and preserving specimens, nests, and eggs for scientific study. Arrangement facilitates locating species by order, color pattern, or systematic listing, and the plates are scaled to aid recognition at a distance.

STEGANOPODES.

Family 1. TROPIC BIRDS. Phaëthontidæ. 2 species.
Family 2. GANNETS. Sulidæ. 6 species.
Family 3. DARTERS. Anhingidæ. 1 species.
Family 4. CORMORANTS. Phalacrocoracidæ. 6 species, 5 subspecies.
Family 5. PELICANS. Pelecanidæ. 3 species.
Family 6. MAN-O'-WAR-BIRDS. Fregatidæ. 1 Species.

The members of this Order agree in having all four toes connected by webs, but in other respects they differ widely in structure and, consequently, in habit. The young of all the Steganopodes are born naked, unlike the young of most of the other water birds, which, as a rule, are hatched covered with feathers and can swim or run about soon after birth. The nests of the Steganopodes are, of necessity, therefore, more complex structures than those of birds whose nests are merely incubators and not cradles as well.

Tropic Birds resemble the larger Terns, when in the air, but their wing strokes are more rapid. They usually nest in holes in the face of cliffs, and lay one whitish egg, marked with chocolate.

Gannets are true sea birds, but, as a rule, do not live very far from the land. When breeding, Gannets are usually associated in great numbers. Their nests, as a rule, are placed on the ground or on cliffs, and one or two chalky white eggs are laid. At this season the birds are exceedingly tame and in localities where they have not been much molested, one may walk about among the sitting birds without their taking flight. Gannets are powerful birds on the wing. Their vigorous wing strokes are interrupted at intervals by short sails. They feed on fish which they capture by diving from the air.

The Darters or Anhingas number four species, distributed throughout the tropical parts of the globe, only one species inhabiting America. This is generally called the Snakebird or Water Turkey in Florida, where it is a common species on the more isolated rivers and lakes. The name Snakebird is derived from the bird's habit of swimming with the body submerged, when the long, sinuous neck, appearing above the water, readily suggests a snake. At other times Snakebirds mount high in the air and sail about, like Hawks, in wide circles. They build a large, well-made nest in a bush or tree, generally over the water, and lay four bluish white, chalky eggs.

Cormorants nest in large colonies, generally on isolated islets, but sometimes in remote swamps. The nests are placed closely together on the ground, in bushes, and less frequently in trees, according to the nature of the bird's haunts.

Cormorants feed on fish which they catch by pursuing them under the water. They dive from the surface of the water like Ducks, or from a low perch, but not from the air, as do the Gannets.

Pelicans nest in colonies, generally on some small island, building their nests on the ground or in bushes, and laying two or three large, white, chalky eggs.

Brown Pelicans secure their food by plunging on it from the air, generally from about twenty feet above the water. The sides of the bill are then bowed outward, the opening widened, forming, with the pouch, an effective net in which fish, twelve and fourteen inches long, are captured.

White Pelicans, on the contrary, feed from the water, scooping up fishes as they swim. At times a flock of these birds may surround a school of small fish in shallow water and drive them shoreward, at the same time actively filling their pouches.

Young Pelicans are fed on fish which they take from the pouch of the parent bird by thrusting their bills and heads well into it and prodding actively about for the food to be found there. Young Cormorants secure their food in a similar manner.

Frigate Birds, of which only two species are known, have a greater expanse of wing in proportion to the weight of their body than any other bird. Their power of flight is consequently unexcelled and they may spend days in the air without tiring. Their feet are as weak as their wings are strong, and are of use only in perching.

The food of Frigate Birds consists chiefly of fish, which they catch from near the surface of the water, or rob from Gulls and Terns by pursuing them, forcing them to disgorge their prey, and catching it ere it reaches the water.

Order V. DUCKS, GEESE, AND SWANS.

ANSERES.

Family 1. DUCKS, GEESE, and SWANS. Anatidæ. 49 species, 6 subspecies.

The Anatidæ of North America are placed in five well-marked subfamilies, the Mergansers (Merginæ), River Ducks (Anatinæ), Sea Ducks (Fuligulinæ), Geese (Anserinæ), and Swans (Cygninæ).

The Mergansers, Saw-bills, or Shelldrakes are fish-eating Ducks and their rounded bills, set with tooth-like projections along the sides, are of evident use to them in holding their prey.

The River Ducks include such well-known species as the Mallard, Black Duck, and Widgeon. They differ from the Bay or Sea Ducks in not having a well-developed web or flap on the hind-toe. As a rule they feed in shallow water by tipping, standing on their heads, as it were, while reaching the bottom for food.

The Bay or Sea Ducks have the hind-toe webbed. They feed, as a rule, in deeper water than the River Ducks, sometimes descending to the bottom in water over one hundred feet deep. During the winter they gather in flocks often of several thousand individuals, and frequent the larger bodies of water.

With both the River and Bay Ducks the sides of the broad, flat bill are set with gutters which serve as strainers, retaining the mollusks, seeds and roots of aquatic plants on which these Ducks feed, while the mud or water taken in with the food is forced out the sides of the bill as it closes.

Geese are more terrestrial than Ducks and often visit the land to nip the grass. This is particularly true in the west where large flocks of, Geese, especially Snow Geese, may be seen feeding on the prairies. On the water they feed over shallows by tipping and probing the bottoms.

Swans also feed from the surface of the water either by simply immersing the head and neck or by half submerging the body, when, with the tail pointed to the zenith, the length of their reach is greatly increased.

In spite of their comparatively short wings the large muscles attached to them give to the Anatidæ great power of flight. Not only do they make extended journeys, when migrating, without a rest, but they attain a speed which is surpassed by but few birds. Some of the smaller species, when alarmed, doubtless flying at the rate of one hundred miles an hour.

In common with other diving water birds the Ducks, when molting, lose most of their wing feathers all at once, and for a time are therefore unable to fly. During this comparatively helpless period the brightly colored males assume in part the plumage of the females and are thereby rendered less conspicuous. With the return of the power of flight, however, they regain their distinctive, male plumage, which is usually brighter than that of the female. With our Geese and Swans there is no sexual difference in color.

Most of our Ducks and Geese breed in the north, some within the Arctic Circle, and winter from the southern limit of frozen water southward. The American Merganser, Hooded Merganser, Wood Duck, Buffle-head, Golden-Eyes, Tree Ducks, and possibly Harlequin Duck nest in hollow trees, at times some distance from the water. The young of the American Golden-eye and of the Wood Duck have been seen to reach the water by jumping from the nest-hole and fluttering down in response to the calls of the parent below. It is said that they are also brought down in the bill of the old bird, but this statement apparently lacks confirmation.

The remaining species of our Ducks, Geese, and Swans, nest as a rule, on the ground generally near water. From five to fifteen and, in the case of the Fulvous Tree Duck, possibly as many as thirty eggs are laid. In color they vary from white to buffy and pale olive and are always uniformly colored. Incubation is performed by the female alone. The males at this period among most Ducks deserting their mate to undergo the partial molt before mentioned. While incubating the females surround their nest with soft down plucked from their bodies and when leaving the nest to feed, this down is drawn over the eggs with the double object, doubtless, of concealing them and of keeping them warm.

With Eider Ducks this down constitutes the larger part of, if not the entire nest. Saunders states that in Iceland the down in each nest weighs about one-sixth of a pound. This is gathered by the natives, who, however, are careful to afford the sitting bird an opportunity to raise her brood without further molestation.

The collection of Eider down thus furnishes an admirable illustration of proper economic relations between man and birds. The down is an important source of income to the natives of the comparatively barren, northern countries in which the Eiders nest. So long as man can remember it has been gathered annually. Still the Ducks continue to return in numbers year after year to the same region, perhaps the exact spot in which they nested the year before.

Less intelligent methods would perhaps rob the bird of its second, as well as of its first nest and, unable to reproduce its kind, the species would become extinct within a comparatively short period.

The evils which would follow such a course are, however, thoroughly understood. The Ducks, in the first place, are encouraged in every way. It is said that should one walk into a peasant's cabin and preempt his cot as a nesting-site, the peasant would gladly give up his bed to so valuable a visitor.
